I have this code:
I have 2 questions:
1.-How can I do to the blue background auto expand to the width of the browser automatic no needed to do in the height. This auto width must not affect the size and position of the accordion.
2.-How can I make to return to original state of the color green of the tabs if you close all tabs because if you see if you close all tabs the last tab opened stay on gray. In other words if all the tabs closed after navigate on any tab all the tabs must have the color green of original state.
Tried to move something in CSS but I just messes the colors.
